This publication relates to a method and a system for producing freshwater through a reverse osmosis process in a submerged membrane system requiring a differential pressure over the membrane system. The differential pressure is provided by introducing gas bubbles in the riser device (2) downstream the outlet (7) for fresh water in the riser device (2). The system comprises at least one submerged, reverse osmosis unit (1), with an inlet (4) for water and an outlet (7) for fresh water, a riser device (2) extending from the outlet (7) of the submerged membrane system to at, above or below sea level and a system for providing a low pressure side for the reverse osmosis process.

A dual-chamber onboard electrolysis system is configured to produce HHO gas for heavy duty trucking applications.

A water reservoir and electrolysis cell combination that has a flow connection between a lower fluid port of the water reservoir and an upper fluid port of the electrolysis cell. The flow connection includes a first conduit with an inner bore which serves as a first flow path for the flow of water by force of gravity from the water reservoir to an outlet for the first conduit positioned within the electrolysis cell. The second conduit is concentric to the first conduit and defines an annular space between the outer surface of the first conduit and the inner surface of the second conduit which serves as a second flow path for an upward flow of gas from the electrolysis cell to the water reservoir.

A dual-chamber electrolysis vessel safely stores HHO gas for use by an internal combustion engine.

A compact portable oxyhydrogen generator has a housing, an end cover fastened on the upper end of the housing for discharging gas, and a bottom cover fastened at the lower end of the housing. A battery module for supplying power, an electrolytic cell module for generating hydrogen/oxygen mixture, a water filtration cell for filtering moisture, and a multi-stage filter baffle for further filtering the gas are sequentially arranged in the housing from bottom to top. A flame retardant core is provided between the filter baffle at the top layer and a gas outlet provided in the end cover. The multi-stage filter baffle is provided according to requirements of a gas filtering index. Water is used as a reaction raw material and an inorganic salt can be used as an electrolyte, such that a normal-pressure hydrogen/oxygen mixture may be to directly generated, and can be produced when needed.
